The Windows key between the Ctrl and Alt keys on your keyboard can do more than bring up the Start menu, try these shortcuts:
Windows Key + D: | Show Desktop |
Windows Key + E: | Windows Explorer |
Windows Key + F: | Find Files or Folders… |
Windows Key + M: | Minimize All Windows |
Windows Key + Shift+M: | Undo Minimize All |
Windows Key + R: | Run… |
Windows Key + Tab: | Select Task |
Windows Key + Break: | System Properties |
Windows Key + F1: | Windows Help |
You can also create your own shortcuts with the free Winkey software from Copernic.

I use C for calculator and N for notepad, among others.
